new details in the case of the teenager stowed away in the wheel of a jumbo jet and survived. And how he broke through security to get in there in the first place. David Kerley from Reagan national airport with the latest. Good morning, David. Reporter: If you're like me, 24 hours later, still scratching your head. How did this 15-year-old survive this high-altitude, low-oxygen, long flight? And what does he thinking? Residents in this Santa Clara neighborhood, telling us overnight, they believe the teen leaves in this house with three siblings and parents. They're really quiet neighbors. Yeah. We really don't hear noises or anything. Reporter: Neighbors say his father is a cab driver. And they only see the family in passing. I see the taxi cab come in and out occasionally. Reporter: Here's what we do know. Saturday, the 15-year-old fought with his family. And at some point, left the house and made his way to this fence, around the San Jose airport. He scaled it to get on to airport grounds, abating security. But video cameras capture him climbing into the plane. It does appear that he did scale a section of our perimeter fencing, under cover of darkness. And remained undetected as he proceeded on to the aircraft ramp and proceeded into the wheel well of the aircraft. Reporter: The wheel well of a hawaiian airlines 767. Officials say he chose the first plane he saw. And may not have realized he was going to be in the air for 5 1/2 hours. And not the air we breathe. But at 38,000 feet, where the percentage of oxygen is a fraction of that at sea level. And temperatures of at least 50 degrees below zero. The plane landed at 10:00 A.M. Hawaiian time. An hour later, crews were startled when someone was coming out of the wheel well. He was weak. He hung from the wheel well. And then, he fell to the ground and regained some strength. Reporter: Still, many questions remain, including why no one spotted the teen on the security cameras at the San Jose airport. A lot of questions about airport security across the country. One report that the boy may have been trying to get on a plane to Africa to visit relatives. We don't have confirmation on that. But he is going to be headed point. There's so many questions. One being how could someone get inside that cramped wheel well
